ASTM D1133-97(2001)
(Test Method)Standard Test Method for Kauri-Butanol Value of Hydrocarbon Solvents
Standard Test Method for Kauri-Butanol Value of Hydrocarbon Solvents
SCOPE
1.1 This test method covers the determination of the relative solvent power of hydrocarbon solvents used in paint and lacquer formulations. This test method is suitable for use with solvents having an initial boiling point over 40°C and a dry point under 300°C when determined in accordance with the procedures in Note 1.
Note 1—Test Method D 86 is used to determine the initial boiling point and dry point for mineral spirits and similar petroleum solvents. Test Method D 1078 is used for pure compounds and narrow boiling range cuts.
1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
1.3 For specific hazard information and guidance, consult the supplier's Material Safety Data Sheet.
